Tenebrescence is the phenomenon that occurs when a mineral changes color after exposure to UV light. The color change is temporary, and can be reversed when the material is exposed to incandescent light. Tenebresence is the name given to a color change induced by UV light and when a deposit of colorless Scapolite from Afghanistan was tested with UV light, the result was remarkable. Colorless gems underwent a profound change of color to a saturated, medium blue. When the short-wave UV light was removed the stones immediately began to fade and returned to colorless within a few minutes. The stone is then ready to go through this cycle again and again.

the discovery of the new Scapolite was both a welcome treat to collectors and a boon for Scapolite itself. As the stone is a desirable rarity . The deposit did not produce a huge quantity of gem material.

Why are users outbidding themselves?

When a bid is placed, this is the maximum amount a user is willing to bid for the product. Our system will then automatically bid on that users behalf, incrementally increasing the bid to maintain their position as the highest bidder, up to the specified maximum.

When there is an icon indicating 'Auto Bid,' it means our system is actively placing bids for the user based on their maximum bid. This may appear as if users are outbidding themselves, but it's simply a result of the system updating the bid to reflect the users maximum limit.

Audit

The Gemstone Sheriff program allows our members to request an audit on any product, which is completed by an independent Gemologist who assesses the accuracy of the item description and pictures.
